Anybody care to quote the part of the owners manual where it says it's "normal" to go into the red under heavy load/hot conditions. This has been in the owners manual of every BM I've owned, go look.
I have actually manually measured the red zone temp on my various cars 115C to 120C which is not going to do anything. I think you honestly need to go right through the red zone and out the other side to mess it up.
I am not sure about cars that got broken by just going into the red I think they only get damaged by going right through it, you need something over 150C to damage stuff like head gaskets, 200C to warp head and over 300C to remove temper on the rings.
Just my thoughts don't flame me.
I was once at the dealer when some woman drove her 318ti in after doing 200Km with no water, there was lot's of burning plastic smoke and when they opened the bonnet all the sensors and plastic had melted right off the engine.
